polycrystal plasticity
Fatigue

We have an open PhD position starting in the Spring or Fall semester 2020 at the Computational Laboratory for the Mechanics of Interfaces at the University of Tennessee – Knoxville. A high quality PhD student is sought to study failure of structural materials under fatigue by developing a novel computational approach that explicitly targets traction equilibrium and displacement compatibility along the grain boundaries.

Modeling the Locomotion of Soft Robots using Discrete Elastic Rods

Dear Colleague,

I write to bring your attention to a recent paper describing the use of a planar version of Bergou et al.'s discrete elastic rod theory to model and simulate a prototype caterpillar-inspired soft robot. The paper just appeared in Soft Robotics:

Nanoscale self-healing mechanisms in shape memory ceramics

shape memory ceramics; nanoscale; self healing; atomistic simulations

Shape memory ceramics, such as yttria-stabilized tetragonal zirconia (YSTZ), offer unique properties including ultra-high operating temperatures and high resistance to oxidation. However, they are susceptible to formation of defects during manufacturing and/or by mechanical deformation. To completely take advantage of their shape memory properties, it is necessary to fully understand the nano-structural evolution of defects under external stimuli. In this study, defect evolution behaviors in YSTZ nanopillars are investigated by atomistic simulations.

Competition between formation of Al2O3 and Cr2O3 in oxidation of Al0.3CoCrCuFeNi high entropy alloy: A first-principles study

Submitted by mohsenzaeem on
research
oxidation; high entropy alloys

We studied the oxidation behavior of face-centered cubic Al0.3CoCrCuFeNi high entropy alloy through first-principles calculations. Three surface orientations were chosen for oxidation, and all the possible combinations of atomic positions at these surfaces were considered. The adsorption energy of oxygen adhesion to the studied surfaces was the lowest for the sites with more neighboring Cr atoms, and the second most favorite site for oxygen adsorption had more neighboring Al atoms.
